CVE-2006-5796 in Soholaunch Pro Edition
Summary
by MITRE
Multiple PHP remote file inclusion vulnerabilities in Soholaunch Pro Edition 4.9 r46 and earlier, when register_globals is enabled, allow remote attackers to execute arbitrary PHP code via a URL in the _SESSION[docroot_path] parameter to (1) includes/shared_functions.php or (2) client_files/shopping_cart/pgm-shopping_css.inc.php.

The vulnerability described in CVE-2006-5796 represents a critical remote code execution flaw affecting Soholaunch Pro Edition 4.9 r46 and earlier versions. This issue stems from improper input validation within the application's session handling mechanisms, specifically targeting the _SESSION[docroot_path] parameter. The vulnerability exists in the context of web applications that utilize PHP's register_globals directive, which when enabled, automatically converts HTTP request variables into global variables, creating dangerous attack vectors. The flaw manifests in two primary locations within the application's codebase, namely includes/shared_functions.php and client_files/shopping_cart/pgm-shopping_css.inc.php, both of which accept user-controllable input through session parameters without adequate sanitization or validation.
The technical exploitation of this vulnerability relies on the dangerous combination of PHP's register_globals feature and insufficient input validation in session variable handling. When register_globals is enabled, any parameter passed through HTTP requests becomes automatically available as a global variable, eliminating the need for explicit variable declaration. Attackers can manipulate the _SESSION[docroot_path] parameter to inject malicious URLs that point to remote code repositories, enabling arbitrary code execution on the target server. The vulnerability's impact is amplified because the affected files are part of the core application functionality, making the attack surface accessible during normal application operation. This type of vulnerability directly maps to CWE-94, which describes "Improper Control of Generation of Code ('Code Injection')" and specifically addresses the scenario where untrusted data is used to construct code that is then executed.
The operational impact of this vulnerability extends beyond simple code execution to encompass complete system compromise and data breach potential. Successful exploitation allows attackers to execute arbitrary PHP code with the privileges of the web server process, potentially leading to full system control, data exfiltration, and persistence mechanisms. The vulnerability affects not only the immediate application but also creates opportunities for attackers to use the compromised system as a launchpad for further attacks within the network infrastructure. Organizations running affected versions of Soholaunch face significant risk of unauthorized access, data loss, and potential regulatory violations. The attack requires minimal sophistication and can be automated, making it particularly dangerous in environments where the vulnerable applications are publicly accessible. According to ATT&CK framework, this vulnerability maps to T1059.007 for "Command and Scripting Interpreter: PHP" and T1190 for "Exploit Public-Facing Application," highlighting the attack patterns and techniques commonly employed by threat actors.
Mitigation strategies for CVE-2006-5796 focus on immediate remediation and long-term architectural improvements. The most effective immediate solution involves disabling the register_globals directive in PHP configuration, which eliminates the automatic conversion of request parameters into global variables. Additionally, implementing proper input validation and sanitization for all session variables, particularly those used in file inclusion operations, provides defense-in-depth protection. Organizations should also consider implementing web application firewalls to detect and block suspicious parameter manipulation attempts. The affected application should be upgraded to a patched version that properly validates and sanitizes session data before processing. Regular security audits and code reviews focusing on input validation and session management practices help prevent similar vulnerabilities from emerging in future development cycles. The vulnerability also underscores the importance of following secure coding practices as outlined in OWASP Top 10, specifically addressing injection flaws and insecure session management. Organizations should implement principle of least privilege for web server accounts and establish robust monitoring systems to detect unauthorized code execution attempts.
